Sleeping through the heavy night starts before bed

You know which night it is. Usually the second one, sometimes the first. You are brushing your teeth and you are already doing the maths on it: what you are wearing, which side you will sleep on, whether you should put something down on the sheet, how early you will wake up to check.

Then you get into bed and you don't really sleep. You sleep on your back because turning over feels like a risk. You wake at three and go to the bathroom, not because you need to, but because you want to know. And in the morning you are tired in a way that has nothing to do with how many hours you were in bed.

If you have been doing this for years and you assumed it was just what a heavy period costs, you are in very good company. Everyone talks about cramps. Almost nobody talks about the two nights a month that a lot of women spend on guard duty.

You have been doing the work yourself

Here is the part worth noticing. The lying still and the checking are a job you are doing with your attention, and it is a job your setup is supposed to be doing for you.

Your attention is also bad at it, because sleep is the one state where you cannot supervise anything. So you compromise. You stay close to the surface instead of asleep, and you call that being ready.

The swap is a small one. Decide it before you get into bed, then stop deciding it.

Two minutes while you are still standing up

This isn't a routine, and it won't take longer than locking the front door. It just moves every decision to before you are lying down in the dark.

• Go longer for the night rather than only more absorbent. Length at the back is what most women are short of, because you move in your sleep.
• Change right before you get in, even if it feels early. The clock starts when you lie down, not when you got dressed.
• Choose something that stays where you put it. If turning over is the thing you are avoiding, that is the thing to fix.
• Leave a spare and a wipe within reach of the bed. Half of it is the walk down the hall in the dark.
• Try one night without the towel, if the towel has only ever been insurance.

That last one is usually the one women resist, and it also tells you the most. The towel isn't doing anything. It is a note to yourself that you don't trust the night yet.

The one that stays put

If what you are really avoiding is moving in your sleep, a pad will always be the wrong tool for that particular worry, because a pad is attached to your underwear and your underwear moves with you. Comfort Panties are the obvious answer to this one night: you pull them on like your own underwear, there is no separate pad to shift, and they cover front to back. You turn over and nothing travels, because the thing is the underwear.

They are made for the heaviest night or two, not for the whole period. That is how most women actually use them.

What the morning tells you

Give it one cycle, and watch one thing only: how you feel when you wake up, rather than whether anything happened.

You don't need a bad night to deserve an easier one.

Because "nothing leaked" was never really the goal. The goal is sleeping the way you sleep on an ordinary night, turning over without thinking about it. If you get one of those on your heaviest night, your setup did its job and you can stop doing it yourself.

Give it a full cycle before you decide it cannot be different for you. The habit of staying alert takes longer to put down than the setup takes to change.
